Notes 1. Available only in the Y versions (products with on-chip I
2. Available only in the V850/SB2.
Remarks 1. Default Priority:
Restored PC:
2. The execution address of the illegal instruction when an illegal opcode exception occurs is
calculated by (Restored PC − 4).
3. The restored PC of an interrupt/exception other than RESET is the value of the PC (when an event
occurred) + 1.
4. Non-maskable interrupts (INTWDT) and maskable interrupts (INTWDTM) are set by the WDTM4 bit
of the watchdog timer mode register (WDTM).

INTKR Key return interrupt
Priority when two or more maskable interrupt requests occur at the same time.
The highest priority is 0.
The value of the PC saved to EIPC or FEPC when interrupt/exception
processing is started. However, the value of the PC saved when an interrupt is
acknowledged during DIVH (division) instruction execution is the value of the PC
of the current instruction (DIVH).
